Plot binary matrix as dot

Hi,
I have this matrix that indicates a location [0 0 0 0 1 0 1 1 0 0 1 0 0 0]. I want to plot the value of 1 from this matrix using dot as the marker. How can I do it?
Thanks.

Another way:
spy(sparse(x));

Does it work for big matrix?
I used it for a big matrix it seems that it is squeezing the figure

When you say "squeezing", what do you mean?
My best guess is that perhaps the aspect ratio of the figure is not what you expect? You could do commands like axis square or axis equal, and see if that gives more like what you expect. (There are other options, as well.)

One guess at what you want. If this is not what you want, I suggest you add detailed explanation.
figure x = [0 0 0 0 1 0 1 1 0 0 1 0 0 0]; x(x==0) = NaN; % Changing the value of x. If you need it preserved, save to a new variable. h = plot(1:numel(x),x,'k.'); set(h,'MarkerSize',24) xlim([0.5 numel(x)+0.5])
